docPrint Pro v5.0 is a great product, it is support both 32bit and 64bit systems.
Here's where we seem to stand.
The user-requested product
The vendor has several products (PDFcamp Printer and docPrint Pro) that are 64-bit but neither is being requested by ERCOT staff.
Is it possible for you to redirect us to an alternative link to download the trial version for (PDFcamp Printer and docPrint Pro). From what I understand these 2 products should be compatible with Windows7 64bit OS. The link below from your email is being block from our network for security reason. If no other download links are available, can you send us the install source through email, you might want to change the executable file extension to something else as our Email system will filter that extension? Thank you for your assistance!
Thanks for your message, PDFcamp Printer x64 v2.5 and docPrint Pro v5.0 are all support Windows7 64bit OS, you can download them from following URLs,
the total file size of these EXE files is more than 20MB, so we feel difficulty to send them to you via email, please understand.
