Error presents immediately at the start of the install.  the only thing requested was to verify language of the installer.

Environment

Release 17.3 or higher (all versions of EEM)

CA Service Management

Cause

8.3 notion has not been configured in a way that the InstallAnywhere installer is able to read correctly.

Resolution

One will need to test if 8.3 has been enabled by examining for this registry entry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem\NtfsDisable8dot3NameCreation

If this entry is not present, creating it should resolve the issue.

This page from Microsoft explains what values to set this key to.

 

Additional Information

Simply testing via fsutil or running "dir /x" is not sufficient to test if 8.3 has been enabled for this scenario.  The installer is checking for the presence of a specific registry entry, which the aforementioned testing methods will not be able to account for.
