Hello Scott Thanks for your Reply....I had already raised a call (https://support.ptc.com/apps/case_logger_viewer/auth/ssl/case=12869275)and got the same answer which I also found while searching the PTC Support KB.I have :
- setup.exe /S /V"/L*V \"%temp%\dtiinstall.log\" /qn" -->Install
- setup.exe /S /X /V”ALLUSERS=1” "/L*V \"%temp%\dtdeiinstall.log\" /qn" -->For Uninstall
But for the Uninstall it needs the setup of the same version that is being Uninstalled and not the later version. We have Updated from 10.2 M030 CPS05 to 10.2 M030 CPS09 and in such scenarios even the Install of Newer version over the older version doesn't actually makes an update but installs a New Version altogether. So there are two version of DTI rather that Updating of the older one in case I directly run the silent install before uninstalling the CPS05 one
For Uninstall it needs the setup from the source Windchill
and for re install it needs setup file from the target Windchill
and there is no possibility of clean uninstall as the configs and all get corrupted sometimes as the registries are not cleaned up even after uninstall...
...Have Found out Alternative ways now to Uninstall via the wmic commands..But the reg cleanup option is still open..
Also Setting of Client Preferences is also an Open Topic ..(e.g the Checkout Prompt,) and the install of specific component of DTI via silent install is still not possible (https://support.ptc.com/appserver/cs/view/solution.jsp?n=CS76711)
hence I was looking out for some Best Practices and experiences across the board..
