When printing a report from RollMaster to Microsoft Excel, you may see the error “Invalid C$Copy”. This usually happens because RollMaster uses a temporary file name when exporting reports to Excel (something like PTE1_XXX). If another Excel file with the same temporary name is already open, the new report export can fail with this error.
How to resolve the error
Check for open Excel files — make sure you don’t have another Excel report open with a temporary RollMaster name like PTE1_XXX.
If you do see a file with that name, either:
Save the first report with a unique file name, or
Close the first report if you’re done with it.
After saving or closing the conflicting file, try printing the second report to Excel again.
🧠 Quick explanation
RollMaster exports reports to Excel using temporary filenames. If Excel already has a file open with the same temporary name, the system can’t overwrite or reuse the name, resulting in the “Invalid C$Copy” error. Closing or saving the first file resolves the conflict so the new report can be created
