ProIV IDE Trouble Shooting 1) Problems with MFC71.DLL after installation After installing ProIV IDE Client, I get the following error: "This application has failed to start because MFC71.DLL was not found. Re-installing the application may fix this problem." I think that this is because the ProIV Bus & Tasks API has been 'Dynamically linked' when it was built. This means that you need to have the MFC71.DLL file in your C:\Windows\System32 dir. This file can be downloaded and installed by clicking on the link below. Download MFC71.DLL from www.dll-files.com You can also read more about it from the Microsoft link: Microsoft MFC71.DLL 2) Timing out while connecting to server If you are working on a slow network or other slow connection then you may have to increase the following parameters to make sure that the ProIV IDE client does not timeout too early. In the ProIV IDE client go to menu Tools/Options/Environments. Each environment has a 'Srv Con Timeout' and 'Client Timeout'. These timeout values may need increasing for slower connections. Try making them both '60'
