Run-time error 13 - Type mismatch

Hi,

I logon on my BPC appset (MS 7.5) successfully.

When I click on a dimension in the CV of the Action Pane, I read this messagge error: Run-time error '13': Type mismatch (on OsoftShare)

If I click on OK the popup is the following...

Closing this window, I receive...

I have a Windows 7 64bit and a 32bit Excel 2010, and for a very long time it works fine.
This morning I first uninstalled PDFCreator 1.7 and I have installed PDFCreator 2.0.

I tried to uninstall all PDFCreator but it don't works.
Also, I tried to register (regsrv32 command) the XceedZip.dll (version 6.5), to re-install the BPC client for Office, but the error is still here.

Have you any ideas to solve this issue?

Thank you in advance,

Marco Minaudo

PS. I receive this messages only on my personal computer. Any other clients on other PC works fine.
