I would need to look at my website hosting the update file. I don't use it other than hosting the update file, so there may be an issue there. Need to find a working alternative.

I had wondered about that; even checked to see if "Never" was an option. Just curious, any idea why when I run the update exe, I get "Unable to determine if an update...

If you run the Update Program.exe in the install folder (i.e. C:\Program Files (x86)\Spreadsheet Compare), then click on the Options tab, you can set check interval in days. If you put 1000 days, then that should hold it off for a while.

Try v.1.41.0 I uploaded last week. I think that fixed the issue.

I have found a colleague who has the same computer I have that has the same issue as you. It seems to be a permissions issue with Excel and the refEdit control that ships with Excel. I was unable to immediately fix his issue, but at least I have a computer with the issue that I work on to resolve this. So give me some time to troubleshoot the issue with him and I will post a solution. One thing you can do is delete the lines with ref... that come up in error as that control is missing. The refedits...

In 'Checking/Correcting References', check that RefEdit Control is checked. If not, browser for it and enable it. For me it is in c:\program files\microsoft office\root\office16\refedit.dll. You can also try the installation troubleshooting section for the same file.

Looks like a refEdit (Excel) control issue. Take a look at the help file, there are a number of workarounds for Excel issues in the troubleshooting section. I tried on my pc with Win 11 and Excel 365 (v2511) without issue.

Hmm. I don't see the same thing. Created two new workbooks (with Sheet1, 2 and 3). Renamed tabs in both, one set with '_Old' added, the other set with '_New' added. Ran compare, no matching tabs found. Clicked Active and only the active sheet from both files was moved. Did compare, no errors.

Does this happen in all workbooks or just one/some? If you can reproduce in a pair of files you can post here, I can download and do a compare to identify the problem. Don't upload anything that has personal information or data you don't mind sharing. Steve
