Wait. Another application is completing an OLE action

Yesterday I installed the PdfCreator but I opted not to install Pdf Architect etc....

At end the PdfCreator was installed but not the PDF Architect 2 etc....

Strangely, in the directory program files was present the directory pdfArchitect.

The big problem was when I open the excel file,

I wait, I wait and wait and at end I have the following message:

Wait. Another application is completing an OLE action

My solution:

I have close the excel file and I removed in brutal mode the directory pdfArchitect.

Now all work well.
