Hello, I’ve got a problem with the code reverse functionality of VP. When I try to reverse my C++ code, an error dialog with the following message occurs: > Reason : Output file from parsing source code does not exist. /tmp/irTemp49663temp/ouf/index.xml If the above file does not exist, please make sure there are execute permission to all files under the following directory: /opt/VP\_Suite3.4/bin/vp\_windows I am using Suse Enterprise 10. Thx… PS: All permissions are set properly. Used VP-Standard Edition with evaluation license. ---

Hello Lettort, It seems the problem related to some of the library required for reverse engineering not appear on your system. Can you try the following steps and see is it working? 1. rename the doxygen under VP Suite /bin/vp\_windows to something else 2. download the doxygen at the following link to the vp\_windows folder [http://files2.visual-paradigm.com/resources/Compiled\_doxygen/doxygen](http://files2.visual-paradigm.com/resources/Compiled_doxygen/doxygen) 3. make sure the newly downloaded doxygen got execute permission. 4. perform reverse engineering Hope this help. Best regards, Rain ---

Hello again. After installing a newer version this bug still remains unfixed. Perhaps you are going to patch the solution into the next version. 😉 Bye ---

Hello, The given link no longer works. Is there another place that doxygen can be downloaded from? Or can it be downloaded from anywhere? Thanks!

Same problem here. I guess from what Im seeing (problem persisting over many years) is no longer being maintained as it is not worth looking at. ---
