file associations restore failed.

[KingMario]

the pdf file was associated with Adobe Acrobat Reader v9.3.2 before i made PDFXV as default PDF viewer.
when i click Restore File Associations in Preferences window, the pdf file type is gone.
that's strange.

You may need to set Acrobat as the default manually in Acrobat if that is what you require, perhaps an update to Acrobat removed the previous association once we were set as the default...

Hard to say for sure.

[KingMario]

the .pdf default entry in registry was "AcroExch.Document" before i set PDFXV as the default viewer. then was changed to "PDF-XChangeViewer.1".
after i click restore in PDFXV, the value is set to BLANK.

maybe it's the problem. but not a big deal, anyway.

Did you use .MSI or .EXE installer to install the viewer ?

[KingMario]

i used the PDFXVwer.exe to install.

fyi, the FullBeforeInstall value of your registry key is:
HKCR
{
NoRemove .pdf = s ''
}
HKCU
{
NoRemove Software
{
NoRemove Microsoft
{
NoRemove Windows
{
NoRemove CurrentVersion
{
NoRemove Explorer
{
NoRemove FileExts
{
NoRemove .pdf
{
val Progid = s ''
val Application = s ''
ForceRemove UserChoice
}
}
}
}
}
}
}
}

To be honest, I'm not sure what you mean "FullBeforeInstall" ?

[KingMario]

To be honest, I'm not sure what you mean "FullBeforeInstall" ?

it's a string value of the registry key [HKEY_LOCAL_MACHINE\SOFTWARE\Tracker Software\PDFViewer\FileAssociations]
maybe adobe acrobat reader 9.0 uses a new mechanism to setup the file association that PDFXV doesn't recognize and record to this register string value.
