3. How will my client's Very PDF printer know it is not a Trial or does this happen automatically when my program with the SDK registers the printer on their workstation?
=========================
After you purchased it, you will get a license key, please set the license key to "RegisterNO" in registry, docPrint Pro will be registered automatically,
HKEY_CURRENT_USER\Software\verypdf\pdfcamp
RegisterNO="Your License Key"
VeryPDF
=========================
loWSH = createobject("wscript.shell")
loWSH.RegWrite("HKEY_CURRENT_USER\Software\verypdf\pdfcamp\RegisterNO", MyLicense)
I put in the registry on a client machine but it still shows the purchase license prompt. Please help.
=========================
You can set following license keys into registry to try again,
For 32bit Windows system,
HKEY_LOCAL_MACHINE\SOFTWARE\verypdf\pdfcamp
RegisterNO="Your License Key"
HKEY_CURRENT_USER\Software\verypdf\pdfcamp
RegisterNO="Your License Key"
For 64bit Windows system,
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432node\verypdf\pdfcamp
RegisterNO="Your License Key"
HKEY_CURRENT_USER\SOFTWARE\WOW6432node\verypdf\pdfcamp
RegisterNO="Your License Key"
You can click right button under above keys, create a "RegisterNO" key with "string" type, set the value to ""Your License Key"".
After you set your License Key to these fields, please print a document to docPrint PDF Driver, then you will not be prompted by registration message box and a demo watermark in output PDF files.

=========================
Is there a way to do this for any computer? How can I know if a workstation is 32 or 64 bit? Can't I just use one entry and do it the same on a 32 or 64 bit?
=========================
Yes, you can always use following item in registry,
HKEY_LOCAL_MACHINE\SOFTWARE\verypdf\pdfcamp
On the 64bit system and UAC option enabled, if you access above registry item from a 32bit EXE application, above registry item will be redirected to following item automatically, you needn't change anything to your source code,
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432node\verypdf\pdfcamp
