Studio 4.20.20 and 4.20.21 Not Working

[IPNDDS]

I don't this this issue is fixed yet.  I have uninstalled all instances of Studio desktop, deleted the program folder and deleted the studio.xxx cache.  I try to install Windows Studio Desktop from the MediaSignage website and at the start of application install, a message pops up saying,

"Sorry, an error has occurred. The application could not be installed because the installer file is damaged.  Try obtaining a new installer file from the application author."

As an Enterprise user, I have been trying to rectify this problem for the past four days.  What needs to be done in order to fix this problem?

Please contact Lawrence on live chat so he can remote desktop to your PC and troubleshoot...

I'm talking to Stein now.  Should I ask for Lawrence?

After running sever tests in a remote desktop, it's been found that v4.15 works just fine but after an upgrade, logging into my Enterprise account poses no problem but launching a sub-account either through the Enterprise portal or not causes the Studio to lock up during loading.

While this may not pose a problem for everyone, apparently some computers are affected by this issue.  Stein said he would report it to the developers as a bug fix.  Being a vocal advocate of improved scheduling, I cannot even test the new feature because of this.

Please keep this post informed of progress.  Thank you.
