Let’s work through it together.
Search practical steps for Excel, the Assist Pro add-in, installation and account access.
Start with the issue you can see.
Try a tool name, error message or phrase such as “ribbon missing” or “activation”.
The Assist Pro ribbon is missingAdd-in
Close and reopen desktop Excel. In Excel, open File → Options → Add-ins and check whether Assist Pro appears in the active or inactive list. If Excel disabled it, note the message and contact support before changing security settings.
Assist Pro buttons are greyed outAdd-in
Check that a workbook is open and that Excel has finished calculating or processing. Try the action in a copy of a small sample workbook. Note the selected cells and the exact tool name if the buttons stay unavailable.
Excel says macros are blocked or disabledExcel
Use the installer and files approved by your organisation. Do not lower Excel’s macro security settings or enable an unknown file. Ask your IT team whether the signed Assist Pro add-in and its installation location are approved.
Excel freezes or runs slowlyExcel
Save your workbook, allow any current task to finish, then close other large workbooks and try a smaller copy. Note the file size, row count, tool used and whether the issue repeats. Avoid force-closing Excel while it is saving.
A tool gives an unexpected resultAssist Pro
Undo if the action supports it, or return to your saved copy. Check the selected range, headers, blank rows and number formats. Try a small sample and compare the result before running it on the full workbook.
A tool cannot find my data or headingsAssist Pro
Check that the data is on the active worksheet, headers are present and there are no merged cells in the selected range. Some tools need a specific column layout. Open the tool guide for its expected inputs.
Activation or licence check did not completeAccount
Confirm that you are online and using the email linked to your licence. Restart Excel and the Assist Pro License Center, then try once more. Send support the exact message, but never send your password or payment details.
The add-in stopped appearing after an updateInstall
Restart Windows and open Excel again. If it is still missing, check the installed Assist Pro version and whether Excel lists the add-in as inactive. Contact support before reinstalling so we can help preserve your saved routines.
A workbook will not open or save correctlyExcel
Try opening a copy from a local folder and check that the file is not read-only or open in another Excel session. If the issue began after using a tool, note the action and keep the original file unchanged for review.
Macro Wizard output needs checkingAssist Pro
Read through the generated steps or code, then test on a copy of the workbook with a small example. Confirm the result against a known answer before saving or using the routine on important files.
