The old version is:
When you try to upgrade a Client from SoftGrid (4.1/4.2) to App-V 4.5 or 4.6 on a machine that is pre-configured for the new version, you recieve an error:
“unable to set security descriptor on global package file(s), error=0”The installer rolls back.
This happens if you apply GPOs or a configuration .Reg File to the client before the upgrade. Therefor: Do not apply any App-V 4.5/4.6 settings to a client befor the upgrade.
