Errors before/during Installation (Including '16-Bit Subsystem' and 'AUTOEXEC.NT')

'Can't run 16-bit Windows Program. Cannot find file...', '16-bit MS-DOS Subsystem', 'Virtual Device Driver', 'AUTOEXEC.NT or COMMAND.COM not suitable', and other errors.


For almost a decade, Maptech used InstallShield as the application of choice to deliver thier software products. It is usually very reliable, and is by far the most widely used application for installing Windows software. However, there are some conditions under which that InstallShield may not operate correctly. This InstallShield Compatibility Repair application is designed to correct system problems which can cause these issues.

MyTopo now employs a different installer technology. Thus, newer products released in 2009 or later do not require this fix.
