Problem Using Quickbooks on 64bit and 32 bit computers

Posted on 2011-09-16
Last Modified: 2012-06-27

A client has Quickbooks 2011 installed on two machines. One machines which hosts the Quickbooks data file is running MS Vista Home Premium 64bits. Quickbooks ran the necessary updates and opened the datafile. Quickbooks is also installed on the otehr machine which is running Windows XP SP3 but when I try to open the company file on this machine I get an error which says the company file needs to be updated contact the quickbooks administrator.

I copied the company file which had been previously opened on the Vista machine on the XP machine but the error is still there.

Does anyone have any idea why? Also is it possible that it could be related to the fact that  one machine is running a 64bit OS while the other is running 32 bit?

>>> is it possible that it could be related to the fact that  one machine is running a 64bit OS while the other is running 32 bit?

No. This error occurs if QuickBooks on one machine is at a different version level (update level) on the other machine.  Make certain that QB is at the same level on both machines (Ctrl-1 in a Company File to see the version). Also I assume both machines are running QB V2011.

With respect to bit level, I regularly open the same file (multiuser mode) on my Windows 7 Pro 64-bit machine as a colleague with an XP Pro 32-bit machine. Bit level does not play into this.

I have ran updates on both machine and both say that they are updated. Yes both machines are running 2011.

Let's do the following things (and please follow carefully):

1. On the hosting machine (Vista machine), make a good backup of the Company File and save it somewhere. Very important step.
2. Do not use the XP machine until later.
3. On the hosting machine, open QuickBooks. Close any files that opened with it. Now you have a QB window with 3 big buttons. Click on the Open Company button and then navigate to the location of the company file and open it. This is to avoid opening an incorrect recent file.
4. Make sure of two things: (a) File -> Utilities -> Host Multi User Access is ON; and (b) File -> Switch to Single/Multi User Mode is set to Single User.
5. Now run File -> Utilities -> Rebuild Data. This will force another backup and do the backup.
6. Once the rebuild is complete, switch back to Multi User mode.
7. Make sure that all is well with this machine and company file.
8. Start QuickBooks on the XP machine. If any file opens, close the file (but not QuickBooks). Now with the big Open Company button, navigate to the company file on the other machine. Do not use Recent here.
9. Make certain File -> Utilities -> Host Multi User Access is OFF on this machine.
10. See if the file opens. If all is at the same revision level, it should.
If problems still occur, uninstall QB on the XP machine, restart it, re-install QB, and update it. Make sure you are using the same QB CD as for the Vista machine. That is: QB V2011, both QB Pro, or both QB Premier, or both QB Enterprise (not likely). Just make sure both are QB Pro if that is the case.

Thank you very much. It worked but it turns out that while it is now able to open the data file but it seems that they purchased a single user.

Thanks again
