Data is stored separately from the programs, so you should not worry that re-installing will adversely affect the data. Make sure nobody is using Inventory Receipts when the re-install is done. You probably will want everybody out of Accpac Plus, just to be safe.

If you are still concerned, then you can make a backup of your data, and also a backup of the \IRASP directory (the Inventory Receipts program files) before doing the reinstall. Nothing will go wrong, but these are the places that will be affected.
