Just installed C10 on my laptop and am getting the following error. Not sure where to look to find out what is missing.

TPL: (PROG01.$$$) Error: ASSERT: %FixClassName: Cannot find class FileSynchronizationClass - C:\ShopWare\PROG01.$$$:1

Of course, this error propogates many errors - one for each procedure:

Error(3): cif$fileopen .CLW The system cannot find the path specified. - C:...\SHOP$SEC.CLW:1

If anyone could shed some light on this, I’d really appreciate it.

Thank you.

Jim

Should have added: Also installed the 3rd party templates needed for the app. I can open the app, just have the cif$fileopen,clw when I compile.

Found it. The problem is with the In-Memory Driver. Will have to reinstall.
