compiled successfully, but cannot run

[lidarfan]

Dear Daniel,
I compiled the program successfully, but when I ran it, I got the error as shown in the attached picture error.png. It seems that there is a problem to call Qt5Cored.dll.

Would you please advise what might cause the error? This is other information for your diagnosis:

1) I am using Windows 10 (64bit), MS Visual Studio 2019 Community, CMAKE 3.14.1, QT 5.12.2. All of them are the recently released software.

2) For QT, I installed the one based on MSVC 2017 64-bit, which is the latest available from QT as well. Please see attached picture QT.png.

3) I compiled the install project successfully (see attached picture compileSuccess.png).

4) I specify the installation project to save all files to a local drive called C:\CC. See the attached picture installedFiles.png.

I wonder whether it is because MS Visual Studio 2019 I am using is incompatible with the QT-based MSVC 2017 64-bit. Many thanks for your help in advance and please let me know if I can provide any additional information.

It seems to be an issue with OpenGL... What graphic card have you? And does the official 2.10 (or the 2.11 alpha) version works on your computer?

[lidarfan]

My graphic card is NVIDIA TITAN Xp.
I tried both 2.10 and 2.11 alpha. Neither can start. However, the 2.6.3 beta can run nicely.

I also tested the executables in another older Dell computer (Win7 64bit, with probably built in graphic card see attached picture). I got the same results (i.e., both 2.10 and 2.11 alpha cannot start, but 2.6.3 beta can). I compiled the github code in that computer and got the same results as well (i.e., compiled successfully, but cannot run).

Is it possible to download the source code for 2.6.3 beta from github? I am curious whether I can compile that on my computers.

Thanks for your advice!

aha, Daniel. I just found this: I ran the compiled program remotely via Windows Remote Desktop Connection and had the error. However, if I just started the program locally, it worked great. So, it seems that the 2.10 and 2.11 beta do not support Remote Desktop while the 2.6.3 does.

I control my computer remotely at the daily basis to get work done. Is there a way to fix this issue in the latest version? Thanks again.

Yep, since Qt 5, remote desktop access is not always supported (actually it is possible to achieve that, but not with any configuration). Same thing for old Intel chipsets.
