Excel - PROPLUS Error

I'm running Win98SE with the MS Office XP program suite.

Since yesterday I haven't been able to open my MS Excel program. The day before that I was editing someone's PowerPoint slide show with embedded Excel graphs. There was some brief error message then, but it seemed to resolve itself. However, now when I try to open Excel it asks for a file named PROPLUS.MSI.

So I tried repairing my computer's ''MS Office XP Professional with Front Page'' file (Control Panel; Add/Remove Programs; Reinstall). When the automatic re-installation process gets to the point where it asks for that PROPLUS file, I point it to my CD ROM (drive D). That contains a CD with the file on it.

However, after a moment the error message ''Error 1706. Cannot find required files'' appears. I know the missing or corrupt file Excel needs is on my CD because I can see it. Also, there are 300+ Office XP files on the CD disk.

I tried resolving these problems with Google searches for information. I've been going around in the ''error loop from hell'' since this morning and I'm running out of steam. The CD I have also has an 89+ megabyte OFFICE97P.EXE file on it. Should I think about deleting my entire Office XP file and reloading it? Scary!

Sidebar: failing a quick excel program fix today, is there a way I can extract just the raw data from one small Excel file I need to use right now? If I can see the data (mostly words and calendar dates) even in MS DOS, I could at least continue my work pending a full Excel fix.

Thanks for any ideas.

Quick fix.

In reply to: Excel - PROPLUS Error

Download the Microsoft Excel 97 viewer (it will work with Excel XP files) from You can view and print any Excel 97/2000/XP spreadsheet you want, but not edit it.

It's an old version, but exactly what you need. The current one from Microsoft requires Windows XP and will read Office 2003 files.

As a more permanent fix try to run Setup from the Office CD, as you did already. If the repair doesn't work, I suggest you first uninstall all of Excel, then reinstall it. If that doesn't help, uninstall the whole Office and reinstall that. If that doesn't help either, it might be time for a manual patch of the registry.

Hope this helps.

Done . . . and better than a trip to the dentist <grin>

I appreciate that painless fix with the Excel viewer. I can again open the XL business file I need to use - today! Amazing how often it's usually knowing the right question to ask instead of even knowing where to look. I spent hours looking for a fix for that missing program file instead of a new viewer! <grin>.

Thanks much for your help.
