Invoking them on a Windows 64-bit machine results in the error:
"\Micro was unexpected at this time"
The same .bat files all work as expected on 32-bit Windows.
The batch files did not account for the fact that 64-bit Windows have parentheses in the path. Those parentheses cause problems for the DOS batch processor.
Attached to this article is a zip file containing modified batch files that work on 64-bit machines. Simply download and extract to the bin directory of your 9.0.1 installation. By default that is C:\Program Files (x86)\Micro Focus\Acucbl901\AcuGT\bin.
The same applies to version 9.1.0. The fixed batch files will be included in version 9.1.1.
