Initial problems with installing the program were corrected by creating a Microsoft Jet 4 Service Pack 8 bottle before I installed Presto. Installing Presto into that bottle corrected the installation problems. While presto runs fine there is a minor crossover error popup that doesn't seem to affect the Presto program. I just dismiss the popup. Note that while I can enter checks, print blank checks, and design checks, online services do not work properly - starts up within the program but doesn't open link to G7 systems. Adding Explorer may correct that problem but I haven't tried to added it to the bottle as I don't need it to run the program.
