when selecting several files and trying to create PAR files by right-clicking on them (Shell integration), MultiPAR does not start.
1) problem in installation ?
Because the right-click menu is shown and the check-box is checked, Shell Extension might be installed correctly. By the way, if you have been used old version 1.1.8 DLL ago, you needed to un-install it at first.
For example, you should check a registry entry in HKLM;
This may conflict with the new entry in HKCU.
Also, I want to check is the path of "MultiParShlExt64.dll" and "MultiPar.exe". They need to be put in a same folder. You check the path of them.
You check the registry entry in;
If it isn't "C:\Program Files (x86)\MultiPar\MultiParShlExt64.dll", something is wrong.
When you target one recovery file and right-click it, select "MultiPar - Verify Recovery Volume". Does MultiPar GUI open ? If it opens GUI, there is problem in a code of invoke creation.
2) problem in running ?
If you try to create recovery files for source files with very long path, it fails. Simply MultiPar does not support 256 or longer path. Those files will be ignored. How is the filenames and the number of files ?
When you specify 62 or more source files, DLL will make file-list in the user's application data path. If so, you search "MultiPar_list.tmp" in your PC, too. Basically, the path is the parent of "save" folder.
