Uninstalling Professor Excel Tools (or any other of our add-ins is quite simple).
- Close Microsoft Excel.
- Go to “Add or remove programs” in Windows. The fastest way is to press the Windows key and start typing “add or remove programs” until the regarding entry comes up. Alternatively type “Apps & features”.
- Now you should see the “Apps & features” window of Windows. Scroll down to “Professor Excel Tools” and click on it.
- Click on uninstall.
Have you deleted or moved the file Professor-Excel-Tools.xlam?
You should do two steps:
- Remove the previous link to the add-in. Therefore open Excel, click on ‘File’ –> ‘Options’ –> ‘Add-Ins’. Make sure that ‘Excel Add-Ins’ are selected and click on ‘Go’. You’ll see a list of add-ins. Click on ‘Professor Excel Tools’. You’ll be asked if you want to remove the add-in. Click ‘Yes’.
- Add ‘Professor Excel Tools’ again. You can redownload it from here: https://professor-excel.com/tools/Professor-Excel-Tools.xlam. Then follow the steps shown in the Quick Install Guide (see download link below).
You’ve once seen the ribbon of Professor Excel and after reopening Excel it’s gone?
- Don’t just double-click on the .xlam file to open it. Use a proper installation, for example with the downloaded setup file (.exe-file) or activate it from with Excel if you have the .xlam-file.
- Make sure that Excel is closed during the installation with the setup-file (.exe)
- You still run into problems (e.g. add-in gone with the next start of Excel)? Locate the file on your drive, right click on it and click on “Properties”. In the lower section of the “General” tab, make sure the “Unblock” tickmark is set as in the screenshot.
It still doesn’t work? Please check these methods: https://professor-excel.com/prevent-excel-add-in-disappear/
If nothing happens when you press any button of Professor Excel Tools check the following options:
- A workbook needs to be open
- Are add-ins allowed? Therefore Click on ‘File’ –> ‘Options’ –> ‘Trust Center’. Click on ‘Add-ins’ on the left hand side. Make sure that none of the three options is ticket. Click ‘OK’ and restart Excel.
For initiating the update please click on About on the right hand side of the Professor Excel ribbon. If the version number (e.g. 1.1) is lower than the current version shown in the update text on this webpage (below), the update should start when you click on “Check for updates”.
Unfortunately, sometimes you’ll receive a message “No new updates”. In such case, please use the following workaround: Clear the cache of Internet Explorer.
- Open Internet Explorer.
- Open internet options by typing internet options by clicking on the small “gear” symbol in the upper right corner.
- On the General tab, under Browsing history, click Delete. If you don’t want to clear all files click on “Settings” and then “Show files”. In the new window, search for “ProfExToolsCurrentVersion.htm” and delete it.
Try starting the update again. Please contact us if the problem still persists at email@example.com.
We are working on a solution and in the meantime we apologize for any inconvenience.
License / Versions
When you buy the full version, you will get a licence key. With this licence key you can unlock the full and unlimited version of Professor Excel Tools.
However, you won’t get access to the underlying source code and VBA macros.
The purchase process is handled via mycommerce.com. Clicking on the Purchase button will guide you to the site.
When purchasing a licence for the full version you’ll get a licence key. With this licence key you can unlock the full version. Therefore, go to About within the Info section. Then click on unlock and enter your licence key.
The software is the same as the trial version. Only the trial version expires after 31 days after the first usage. You can redownload the trial version any time and enter your purchased licence key again.
Yes, we still update Professor Excel Tools (the history is available when you scroll down). And yes, it works with newer versions of Excel, such as the Office 365 subscription. We are heavy users ourselves so we’ll try to keep it working.
However, we don’t legally guarantee anything. You get the add-in “as-is” and can’t guarantee “eternal support”. That’s mainly because we also rely on Microsoft and their specifications. Also, please make sure to test the trial on your local computer.
So, in a nutshell: Yes, as of now, it should work with the newest versions and we try to keep it that way.
Functionally, there is no difference between the free trial version and the premium / full version of Professor Excel Tools. The trial is fully functional. Actually, it’s the same installer and source file. So, if you’ve downloaded the free trial, there is no other change required once you’ve purchased the full version.
The trial version only works for 7 days. After that you have to enter a license code.
There is, however, one exception: The Professor Excel built-in formulas (such as “=PROFEXSheetName()”) still work in the trial version after it has expired.
One more comment: Please test the trial before purchasing the premium / full version.
Summary: No, there is no virus in Professor Excel Tools.
Professor Excel Tools offers a lot of features, some of them require some procedures that might be mistaken to be harmful.
- The sharing features need to save a temporary file on the hard drive. After sharing, the temporary file is deleted.
- Or the update function: When you click on “update”, it downloads the new version, installs it and deletes the old version. Some virus scanner mistake that for a “Trojan horse”.
To make it clear: There is no virus in Professor Excel Tools. We have no interest in harming you or your computer in any way. We earn money by selling one-of licenses. That’s it.
The website “VirusTotal” can check files and provide a summary. For Professor Excel Tools, 2 out of 61 virus scanning software might detect a threat. Or in other words: 59 out of 61 virus scanners don’t think Professor Excel Tools is harmful.

Please note: We are working on an undo function. This is not supported by VBA and it requires individual approaches for each feature.

Bug fixes and performance improvements.
Version 1.3, release date: February 14, 2017
We are excited to announce a major update introducing many new and improved features:

Applying is even easier: Select cells you want to format and click on one of the Quick Format Buttons.

- Export Manager: Export one or more worksheets to a folder. You can define one input variable to change each time.
- Calculate selection, force to number, insert IFERROR and ROUND now work on array formulas.

- Layout Manager: Change the direction of outlines/groupings.
- Swap two cells: You can define within the settings, if other cells linking to your two swapped cells should adapt or not.

Version 1.2, release date: June 26, 2016
We are excited to announce a major update introducing many new and improved features:
- “Reduce File Size” now shows you the size of each worksheet. You can then select which worksheet you want to reduce.
- New function: “Name Manager”. The built-in name manager only shows a small portion of the names in your workbook. With our new name manager you will see all named ranges and you are able to remove them separately.
- We removed the function to swap comma and point (usually people use the function “Force to number” instead). Instead, we introduced a function to swap two cells. The best part: any cells directly linking to one of the swapped cell will automatically adapt.
- New function: “Remove Conditional Formatting” rules but keep the format. Just select the cells with conditional formatting and press the button “Remove Conditional Formatting”.
- This function is very exciting: press Ctrl + Alt + c on the keyboard for copying the current cells. You can then use one of Professor Excel Tools paste functions or the normal Excel paste options. The best part: copy the last range again by pressing Ctrl + Shift + c.
- Many new formulas:
- PROFEXAuthor: Insert the name of the author.
- PROFEXDateCreated: Insert the date on which the workbook was created.
- PROFEXDateLastSaved: Insert the date on which the workbook was last saved.
- PROFEXFileSize: Insert the file size of the current workbook.
- PROFEXFolderName: Insert the folder name of the current workbook.
- PROFEXLastSavedBy: Insert the name of the person who last saved the workbook.
- PROFEXNumberOfHiddenWorksheets: Insert the number of hidden worksheets.
- PROFEXNumberOfWorksheets: Insert the total number of worksheets.
- PROFEXWorkbookPath: Insert the workbook path.
- Insert formula: when you insert a PROFEX formula through the insert formula window which can also be created with built-in formulas, Professor Excel will insert the real Excel formulas instead of PROFEX formulas. That way, users without Professor Excel Tools won’t see error messages.
- We have moved the “Workbook Info” button to the Info section.
- Improved sharing buttons.
- Minor bug fixes and performance improvements.
