Hallo everyone.  
Does anybody compiled a project for 64bit in VS2017?  
I’m trying to compile a project for 64bit the last 2 days with no success.  
I tried everything written in forums and github, but nothing. (register, unregister, install both 32 and 64).  
Versions 5.3, 5.2.4, 5.1.0, 5.0  
While in 32bit everything works OK, when I try in 64bit either I get message that ocx not registered or that AxMapWinGIS not found.  
If anybody can give detailed instructions it would be great.

Hello @mapl

I’m sorry, but it’s not clear to me whether you’re having trouble building the 64-bit ocx? or using the ocx afterward in another project?

Regards,  
Jerry.

Thanks for your reply,  
I have problem using the ocx.  
I installed from github a release of mapwingis for 32bit. I make my own 32bit project in [vb.net](http://vb.net) using the ocx with no problems.  
Now I want to compile my project targeting 64bit. So, I installed also the 64bit version of same release of mapwingis, but when I try to compile I get the errors described earlier.  
I tried using vs2017 32bit and vs2017 64bit.  
I tried also all releases from 5.0 and afterwards.  
Any suggestion?

Thanks
