Problems uninstalling Ansys V11 Multiphysics 64 bit on windows os

Problems uninstalling Ansys V11 Multiphysics 64 bit on windows os

(OP)
Hi
 
I have a quick question regarding Ansys running on windows 64 bit OS with 64 bit architecture dell pc.

I am using  Ansys MultiPhysics V11 64 bit on winndows XP  . I wish to install the new service pack SP1 version  of the software, released today,  it too is 64bit , but I am unable to uninstall the existing original V11 version I just get a an error unable to unstall/ delete. I spoke with the Ansys tech support. They claim it’s a windows xp issue.


They said that the registry 32 bit diagnostic may need repairing or cleaning up.
I had a look through the dell diagnostic resource cd but it seem to be only applicable to hardware repair.
Can anyone  suggest any command lines in windows or software programs  which I could  use to carry out such a repair?


regards

Hi,
please take what I'll say with necessary precautions:

you can simply erase all the installation directory of Ansys, and then manually clean the Registry from all the entries referring to Ansys. In the "HKEY_CURRENT_USER", or "HKEY_ALL_USERS", you can delete the keys almost without fear, because what is recorded here are the user's preferences/settings; as far as I know, as regards Ansys there is also no problem is deleting the keys in the "HKEY_LOCAL_MACHINE". Drawback of all this is that the Install/Remove Applications in the Control Panel will not be aware of what you do and will report a wrong situation.

Regards
