MemoQ (any version) does not want to launch on my computer (Windows 10). After MemoQ 2015 froze during a translation, I restarted Windows. This usually resolves most issues, however neither version of MemoQ that I had (2013 or 2015) would open, I would only get a general error message with the following content:


Activator version mismatch


em MemoQ.Activator.Activator.pInit(ProductGroups productGroup, Boolean tsManager, Edition requestedEdition)
em MemoQ.ActivatorStartupController.Initialize()
em MemoQ.MainWindow.Main(String[] args)

I am convinced this has to do with a corrupt file. I have tried deleting the Preferences.xml file in the Roaming folder as well with no success. Any advice would be appreciated!

Have you tried uninstalling and then reinstalling? This will usually fix corrupted file problems. Be sure to create a restore point first.

Try erasing C:\ProgramData\MemoQ Oct 8, 2017

Hello, just received the same kind of problem.

Simple uninstalling/reinstalling didn't work. So I've tried removing C:\ProgramData\MemoQ folder and reinstalled MemoQ.
Please let me know, if this works for you.
