I'd like to use Graphviz from http://graphviz.org. My system is Windows 7 Professional, 64bit, SP 1.
After standard installation I get the following error message twice when invoking dot.exe:
dot.exe - System Error
The program can't start because graph.dll is missing from your computer. Try reinstalling the program to fix this problem.
dot -V shows the version (
dot - graphviz version 2.30.0 (20130114.0323)) after the two error messages in the console.
After the first message, the console shows
Warning: Could not load "C:\Program Files (x86)\Graphviz2.30\bin\gvplugin_pango.dll" - can't open the module. This message is repeated after the second popup error message.
This also happens with the current development snapshot version. Setting the path environment variable to include "C:\Program Files (x86)\Graphviz2.30\bin" does not help. Running
msiconfig /a graphviz-2.30.msi results in a permission error. Running
msiconfig /a graphviz-2.30.msi from an Administrator command prompt succeeds, but the problem described above persists.
Upgrading .net to 4.5 did not help.
Thanks a lot, Carsten
