Hey Andr3s_Br3n3s,

When I saw that it is very slow even for a new empty project + empty uir (see the figures I attached above)
and for any other project I have opened I implied that the problem is not with my project.

Some details about my project:

It is an academic application for analyzing spectral data. I use one main big file (~4000 code lines) and 3 other function files. As far as I know, I do not load any dll. 

The project includes: <windows.h>, "toolbox.h", "progressbar.h", <analysis.h>, <utility.h>, <ansi_c.h>, <cvirte.h>
<userint.h>, <shellapi.h>, "Raven.h", "functions.h" , "ucsf.h"

I also use shell32.lib (as library file) and progressbar.fp (instrument file)

Why do you mean by open an example?

Thanks a lot!

I saw the image, Raven.exe is only consuming 476 K, this is weird.

About the example, I was referring if you go to help, find examples and try to run an example that comes with LabWindows CVI.

I think you have tried already.

Unfortunately today I also tried to repair CVI and the problem remained the same.

I even try to uninstall, and then install again and it remained the same.. 😕

I actually did not try an example that come with CVI, I will try it tomorrow.

Thanks so much for trying to help!

Another thing to try is to close other programs, like e.g. TeamViewer. Maybe it has an influence, who knows...

[Edit] You could also try temporarily disabling antivirus program to see if it makes any difference

Hey! So in my university there is a network of strong computers with CVI 2015 installed for a purpose of delivering a course in CVI (in my office it is CVI 2013).

In order to check whether I personally did something wrong I asked a student to open a very simple uir (one button) and to try to work in debugging mode in this stations. Weirdly, the same problem occurred in all the computers. He said that the situation was completely different from when he did the course one month ago. CVI barely work in debugging mode even without a uir and with only one single "printf" command in the int main().

The only thing in common is that trendmicro (an anti virus) is installed, but unfortunately the university does not let
us disable it and I'm not sure it is really the problem. I closed any other thing I could and it's still works very slow 😞

I asked the computer supervisor at our university to unload Trendmicro antivirus (unfortunately we are forced to use this annoying antivirus), it caused the debugging to work perfectly fine as it worked before. 

Thanks for anyone who tried to help so far!
