Basic functionality = the *run* button not working

[Hans82031]

I just want to assemble a a number of pdf files into one document.
My procedure:

• setting up the file list as usual
• defining the output file
• hit the "run" button but nothing is happening: . no progress in the run bar . no file produced I'm not sure: -is it mandatory to fill anything else? e,g,, the other settings that are listed? Please help: I#m working on a Tax Declaration: I did not have this problem last year, with an older version of PDFsam Thanks so much.

Further to my trying to work successfully with PDFsam, I installed the 32-bit Version of PDFsam (v.3.3.7). I was successful to produce the merged file. I appreciated the increased clarity (e.g. no columns except the necessary ones, like filenames, date of the file, One problem I encountered: I entered an illicit file-name, using a colon {:] which prevented the run command to function. Would it be possible to issue the error warning Windows issues in these cases? Greets, Hans
