When attempting to install Symantec Encryption Desktop (SED) 10.4 MP1 HF1, one computer keeps getting a 1603 error.
PGP Desktop requires Internet Explorer 5.01 or higher
SED 10.4.0 MP1 HF1
Windows 7 64-bit
Internet Explorer 11
During troubleshooting, when attempting to upgrade .NET to 4.6.1 we received the exact same error.
Something on that computer was causing the same 1603 error and message when running any msi installer.
Reinstall the OS on this trouble computer.
