I renamed all 4 files. My QRTALW90.qrw had a date of Sept07, but the QRTALZ90 was Mar6/08.
Now when I try to install the SP I get the following error message: "To install this SP, you must be logged in as a Windows User that installed or runs Adagio Ledger. Current User [swilson} does not have the Report Tables file [M:\qrasp\QRTALW90.qrw]."

Do I change the file names back?
