After installing the Access Agent on my Win7 PC 64bit, whenever I try to open an existing Excel file using Excel 2010 (using the PC, not the iPad) by double clicking on the file, Excel waits 20-seconds before opening. There is no obvious disk action or cpu utilization during this time. If I simply open Excel directly, it opens immediately, and if I then select a file to open, it comes up immediately. The problem exists even for an xls or xlsx file with little to no data in it. The files are on the PC, not the network. If I uninstall the Access Agent, the problem goes away, then comes back when I reinstall. No other application seems to have the same problem.
