Reinstall Solid Edge ST7


I recently had ST7 stop on me saying that a file could not be opened, I tried to unistall and re-install but the uninstall process stopped 20% along the way. I then managed to unistall with Revo Uninstaller Pro. But now when trying to reinstall I get the message that it is already installed and has to be removed before I can reinstall... Have spent best part of three days and have given up so any help please..

GTAC Solution Center article 002-7005960 covers how to manually uninstall Solid Edge after a failed uninstall.


I have cut and pasted the body of the article below for your convenience:


Manually uninstalling Solid Edge after failed uninstall

When attempting to uninstall Solid Edge, the uninstall fails and Solid Edge is
not fully uninstalled. How to clean up and manually finish uninstalling Solid
Edge after a failed uninstall?

Hardware/Software Configuration
Solid Edge

If you have issues with uninstalling Solid Edge then you will need to perform a
manual uninstall:

1. Manually delete the Solid Edge program folders typically in C:\Program Files
or C:\Program Files (X86).
2. Manually delete the Solid Edge user preference folder %APPDATA\Unigraphics 
3. Manually clean up the registry by deleting any Solid Edge registries in the
following locations:

HKEY_CURRENT_USER\Software\Unigraphics Solutions

HKEY_LOCAL_MACHINE\Software\Unigraphics Solutions

HKEY_LOCAL_MACHINE\Software\Wow6432Node\Unigraphics Solutions

4. Reboot the workstation.

Solid Edge should now be completely uninstalled and ready to reinstall Solid

I have managed to do all and am happy, thanks for reply. Where does SE hide its saved drawings or have I lost all my work?

Hi there,


Have you done a Windows Search for files with the extension ".dft"?.......these are user managed, so should be saved to a known location outside of the application folder.

If the search doesn't find any files, then they are likely to be gone forever.
