I am using WPI 6.4.1 on Windows XP SP3. Reg files applied via either Registry Before or Registry After (I've tried both) are not really being applied. The following code is written to config.js via the WPI config interface prog[pn]=['Nitro PDF Professional v5.3.3.6']; desc[pn]=['PDF writer/editor/printer/reader']; uid[pn]=['NITROPDFPROFESSIONAL']; dflt[pn]=['yes']; cat[pn]=['Applications']; forc[pn]=['no']; cond[pn]=['FileExists("%wpipath%\\Install\\5_Office\\NitroPDF\\nitro_pdf_professional.exe")']; cmd1[pn]=['"%wpipath%\\Install\\5_Office\\NitroPDF\\nitro_pdf_professional.exe" /s /v"/qb"']; rega[pn]=['"%wpipath%\\Install\\5_Office\\NitroPDF\\NitroPDF5_serial.reg"']; pn++; The progress window shows a "?" next to the Nitro PDF entry upon completion. If I manually run the reg file, it works (i.e. it registers my product). Any ideas about what might be wrong here?
