What i am trying to do is to check if this key NOT exists, run additional instalation, otherwise skip it:

Set Variable AMYUNI to
Check Registry Key HKLM\\SYSTEM\\CurrentControlSet\\Control\\Print\\Environments\\Windows NT x86\\Drivers\\Version-3\\Amyuni Document Converter 2.51\\Driver\\ into AMYUNI

if Variable AMYUNI Equals UNKNOWN$TYPE
MessageBox: .., The value exists, but is of an unknown type
end
if Variable AMYUNI Equals BINARY$VALUE
MessageBox: .., The value exists, but is a binary type that cannot be read with this command.
end
if Variable AMYUNI Equals NO$VALUE
MessageBox: .., The specified key exists, but the specified value does not exist
end
if Variable AMYUNI Equals NO$KEY
MessageBox: .., The specified key does not exist
end
if Variable AMYUNI Equals READ$ERROR
MessageBox: .., An error occured during the read operation (check access privileges).
end
if Variable AMYUNI Equals acpdf251.dll
MessageBox: .., already
else
Run Program $TARGETDIR$\\install.exe "Printer" -n"Company Name" -s (WAIT)
end


I am always getting *The specified key does not exist* even when the key is there.

Any help will be greatly appreciated

I might know what your problem is:

In the Check Registry window, you are setting the Key field to:

SYSTEM\\CurrentControlSet\\Control\\Print\\Environments\\Windows NT x86\\Drivers\\Version-3\\Amyuni Document Converter 2.51\\Driver

and the Value field empty. So your Check Registry command is actually checking for the existence of the default value of Registry Key:

HKLM\\SYSTEM\\CurrentControlSet\\Control\\Print\\Environments\\Windows NT x86\\Drivers\\Version-3\\Amyuni Document Converter 2.51\\DriverTo solve this, just write into Key field:

SYSTEM\\CurrentControlSet\\Control\\Print\\Environments\\Windows NT x86\\Drivers\\Version-3\\Amyuni Document Converter 2.51

and Driver in the Value field.

Hello,

I am having a very similar problem with Check Registry. I want to check for the existence of a key in the location HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall and put the result into a variable. I am leaving the Value field in the Check Registry dialog empty so that if the key exists I should be receiving the default value which is NO$VALUE. I created a quick test installer that I can run repeatedly. I have been able to confirm that if the key I am testing for has no spaces, it returns the expected NO$VALUE, but if the key has spaces it returns NO$KEY. Therefore I must be having problems defining keys with spaces.

This returns NO$KEY even if the key is there:

~InstallAware Clipboard Data~
~Check Registry~
~{82770485-A981-401D-B2CB-5D1CE9B0E837}~
~BIOPDFWRITERINSTALLED~
~2~
~SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\PDF Writer - bioPDF_is1~
~~

This returns NO$VALUE which is what I would expect.

~InstallAware Clipboard Data~
~Check Registry~

~BIOPDFWRITERINSTALLED~

~SOFTWARE\Microsoft\Windows\CurrentVersion\WIC~
~~


How do I deal with spaces in the key name?

Thanks
