Hi Steve,
If you run a "Inventory by Machine" usage report, there is a column for version. You can sort by this column by clicking on the word "version" at the top of the report. All of the machines running version 7.01 are then grouped together. The report will also show the last time that the version was used on that machine. When you set the report options, you cannot filter by version number, however you can filter by product.
HTH,
