Hello everyone. My situation is that I'm getting an error of "The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine". I'm getting this when trying to install an app that I did with Visual Basic 2008 using an Access 2007 Db. I had this error before in my first attempts to install the app. I have learned of a couple of conditions that will cause it. First is if AccessDatabaseEngine.exe isn't part of the solution, then that will generate that error. Second is if AccessDatabaseEngine is part of the solution but the app/solution is running on a 64 bit OS then it's error city. So to take care of the second scenario I had to set compile to x86. So like that the app was working on all of the computers that I was testing the app on. It worked on Vista 32, Win7 32, Win7 64. But the app has evolved a bit so I uninstalled it and reinstalled it on the same computers as before. I have two win7 64 computers that I've been testing all the while. Now on one of them I'm getting that "The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine" error. I don't understand what the problem is. I verified that AccessDatabase.exe is on the machine. The app is compiled x86 style. I have uninstalled and re-installed it many times and have no idea what to do next. Can anyone please help me with this?
