Hi I was using "Access 2003 VBA Help" in the past months. It is useful and works fine. Yesterday my workstation is replaced to a new PC, and I downloaded that hep file again from MSN and installed it. When I click MSOHELP.exe it did not show up. I checked the "System requirement" and noticed that it works for Service Pack 3. However I just installed Service Pack 4 in order to add fonts. I am wondering whether or not the pack 4 caused problem to run the help file. The help file that I downloaded is "Office 2003 Editions: Access VBA Language Reference" and downloaded from "http://www.microsoft.com/downloads/thankyou.aspx?familyId=0447c5a0-5e58-4e69-b90e-c42ec7dbf887&displayLang=en&oRef=http%3a%2f%2fwww.google.com%2fsearch%3fhl%3den%26q%3dAccess%2b2003%2bVBA%2bhelp%26btnG%3dGoogle%2bSearch" Google group, like here, is the best place for help when I can not find answer from the above-mentioned help file. Thank you for your help and instruction!
