Install of pgiwsx64-sua-721.exe fails to install correctly given what appears to be security permission problems. Program will not uninstall and acces to respective folders is denied because of security problems. Most items end up being owned by System even though the install was “Run As Adminstrator”.
We have a problem with SUA installation on Vista. I assume you install on a Vista? We will let you know as soon as we have more information. Please contact firstname.lastname@example.org for a workaround.
Here is a workaround:
After the failed install, take ownership of /opt/pgi and all subfolders and be sure you have access to all subfolders. Rename /opt/pgi. Run uninstall. Rename back /opt/pgi. Run install again.
Install should now succeed.
