csluder , I'm sorry to hear about that.
1. Does this occur with the same installer, or are your staff members individually downloading the installer?
-> If it's the same installer, and in general, does it help if you acquire and try to install Enscape via the installer I uploaded here?
2. Does it make a difference if you try to run the installer with administrator permission/rights?
3. Is your windows fully up to date as in, all the latest updates have been installed?
4. Was anything adjusted infrastructure-wise or on the machines themselves that you could think of which may affect this?
Thanks a lot in advance!
