Hello.
The answer to your question, when using Workbench 12.1.03.309, is
Running executables is not allowed: Test.exe
I00020110: File \Re-Hosting\Test.exe;0 checked out to WIN-RFS1LPK5BSI\\C:\Users\Administrator\.cascm\workspace\.metadata\.plugins\com.ca.harvest.workbench\waCache\waC-WIN-RFS1LPK5BSI-24-197-47405\Test.exe.
I00060080: Check out summary: Total: 1; Success: 1; Failed: 0; Not Processed: 0.
Best regards,
Ricardo Bernardino
EDIT: The file is, as shown in the quote, checked out in Browse mode to a temporary directory, but due to a failsafe is not possible to execute it directly.
