How to make a .exe 64 Bit useable
-
Hi, I made a tool to read a .mdb File, everything works fine except on a 64Bit Machine... To connect to the database I use OLEDB 4.0, but it seems that 64x does not provide this. How could I compile this compatible?? :doh:
OleDbConnection con = new OleDbConnection(
@"Provider=Microsoft.Jet.OLEDB.4.0;
Data Source=" + lblDATABASE.Text);
con.Open(); -
I had a similar problem and strangly, by adding an App.Config file to my project (even if it is just empty) the connection then works. Right click your project, choose add item --> new and find the template 'config', normally it should automatically name it App.config. Press OK. recompile and try again.

Yeah I already tried this, but doesn't work.. I tried "any cpu" / "x86" / "x64" to build.
You have to set it in the "project properties", in the "build" tab, "platform target". I had the same problem with an old application using access, and it worked fine for me.

Thanks for your replies, it seems that the .exe need the manifest. Now it works =) /closed

OK, I don't know what you did that required a manifest, but this problem, as you decribed it, only needed to be compiled to target x86 CPUs. The reason why it doesn't work is because there are no 64-bit providers for Access databases. Since you can't mix 32-bit and 64-bit code in the same process, using an Access database will fail.
