Sometime in the past month a change to my system has resulted in me being unable to add or remove a lot of applications. I first noticed the issue when trying to install Quicktime 7 - the installation just hung when the installshield started. Since then I have tried to uninstall the following applications unsuccessfully;
Mind Manager X5 Trial
Google Desktop Search
All of these uninstall processes get so far before just hanging unrecoverably. I have also installed Norton Internet Security in the past month. I have tried to install and uninstall applications when the firewall and antivirus are disabled but I still have the same problems.
I have a suspicion there is a problem with installshield but I do not understand how an installshield issue could affect multiple programs.
Does anybody have any idea what may be wrong? I do not know where to start to fix this issue so I would appreciate any advice.
In addition - I've just tried to load system restore but the application will not start. This may mean the problem is with Win XP and not the applications.
I am running Win XP.
Kind regards, Simon
