I was trying to install McAfee ePolicy Orchestrator 4.5 on a Windows Server 2008 R2 box and got the follwoing error message:
“The 8.3 naming convention is required for installation. Click “OK” to cancel this installation and enable the 8.3 naming convention before proceeding.”
I didn’t realize that with Windows Server 2008 R2 disabled the 8.3 file name convention (this may have been done in earlier versions as well, but didn’t check that out). You can enable the 8.3 naming convetion by doing the following:
1. Open Regedit
2. Navigate to HKLMSYSTEMCurrentControlSetControlFileSystem
3. Change the value on NtfsDisable8dot3NameCreation to 0
4. Reboot the server
