This usually means there is a problem with the installer reading the files the contents of the disk. One suggestion is to manually copy the contents of the disks to a temporary install folder:
1. Create a folder names age3install on your local hard drive.
2. Manually copy all the files from the CDs to that folder.
3. There may be a few small, oddly named files that can not be copied; this is ok.
4. Once they are all copied over, you can then try to run the setup.exe in that folder.
As another option, I did a a bit of searching turned up a MS support article about this error message with another product, and I wonder if the solution presented for it may help with Age3. It suggested you may receive this error if a local security policy has been set for the following:
|Devices: Restrict CD-ROM access to locally logged-on user only|
You can check this by going to Control panel => Administrative tools => Local Security Policy, then in there
Local Policies => Security Options. You want "Devices: Restrict CD-ROM access to locally logged-on user only
" to be set to disabled. You can also set this by setting the following registry entry to zero:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\WinLogon - AllocateCDRoms
