Trouble Running Solver Under IIS about or-tools

[lperron]

I would expect 64b versus 32b libraries. Alternatively, we require visual studio redistributables libraries. (vs2013 or vs2015 depending on the archive you used, or the compiler you used.

More information: I have got it successfully running under IIS on my own PC, so it's
just the company web server it won't run on. Will update this issue if I find out what
the problem is.

I have found the solution: the Microsoft Visual C++ 2010 Redistributable Package has
to be installed on the web server. I am using the 32-bit version of the DLL, so the
one I needed was at http://www.microsoft.com/en-gb/download/details.aspx?id=5555 .
The issue is described at http://www.laschinger.net/?p=233 . It would be a good idea
to mention this issue in the manual - it took time to nail it down.

Hi,
I have the same problem, but I don't have access to install C++ Redistributable on
server. 
Tried to put msvcr100.dll and msvcp100.dll on bin folder, without sucess. 
Suggestions?
Thanks!

Hi Daniel - it's probably better to send your question to the mailing list at https://groups.google.com/forum/?fromgroups#!forum/or-tools-discuss
. FWIW I think your issue is political - not technical. You need to either persuade
the owner of the web server to put the C++ Redistributable package on there, or use
a different web server.

Solution is to install redistributable on the server.

It really helped! I changed the ISS on x64 in Visual Studio options and it worked!
Thank you.

Hello,
I'm experiencing a similar issue. IIS crashes immediately when creating or calling the Solver model.
Both in IIS and IIS express. I believe all the parameters are set correctly to 64-bit: VS build (x64) and IIS application pool (32-bit =false).
I removed all old version of Visual C++ Redistributable Package and installed 64-bit for VS2015.

Any tips?

Hi @GuyBenhaim , any tips on how did you solve your problem?

As far as I remember, there was an issue of providing a wrong vector of start points for the vehicles, the other was to make sure all settings are 64b : IIS, Project/CPU Properties in VS
