Fatal error when trying to uninstall Test complete

[vijaygup16]

Hi,

I was trying to install TC new version 15.42.09, halfway through I got an error and had to reboot my system. But after that I am neither able to install the new version or uninstall 15.0.379 the old version and even not able to upgrade . I am not able to uninstall from Programs and Features also. Can someone please help?

The error is :

Fatal error

The uninstallation log is empty.

The installation program will be terminated.

Can someone please help me as soon as possible ?

The error is :

The uninstallation log is empty.

The installation program will be terminated.

I get the same error when I try to install new version or delete old version.

Your TestComplete installation could be corrupted. I suggest you download it again. If you're still facing the same issue, then log a New Support Request.

There instructions here, Installing TestComplete in Silent Mode, to uninstall.

Open a Task Manager and see if you have an older version of TestComplete still running. Additionally you may want to check you registry keys for any reference to the older version of TC. Although I can't recall if the error I received was the same as yours, I did experience a similar upgrade issue when moving from TC 14 to 15 and this was the workaround.

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

right-click on the 'Uninstall' folder and then Find 'testcomplete' and delete any folders referencing the old version. If you aren't comfortable using regedit.exe, or don't see any old versions, just wait to see what SmartBear says.

Need to add more point to addressed the issues 

1. Check via the Services console whether the TestComplete 14/15 Service is running. If it is running, please stop the service.

2.Remove the above mentioned registery 

3. Check whether the TestComplete folder exists in the following location: "C:\Program Files (x86)\SmartBear\". If it exists, delete the folder.
