Not finding previous PostgreSQL installation

Hi all,

I'm trying to find the version of previous postgresql installation with the following code:
EnumRegKey $1 HKLM "SOFTWARE\PostgreSQL\Installations\" "0"
MessageBox MB_OK "Installation: $1"
${if} $1 != ""
ReadRegStr $PG_OLD_VERSION HKLM "SOFTWARE\PostgreSQL\Installations\$1" "Version"
.....

I have followed this example.

I have checked with Registry Editor and the entry seems to exist (HKEY_LOCAL_MACHINE\SOFTWARE\PostgreSQL\Installations\postgresql-x64-9.3).
However $1 is always empty and never enters the if.

I have also tried EnumRegKey $1 HKLM "SOFTWARE\PostgreSQL\" "0" and in this case it prints "Installations" so it seems to find the root.

Any suggestions to solve this problem?

Thanks in advance,
Anna.

If you support 32 and 64 bit psql then you must use SetRegView to read from both registry views probably.

Thanks Anders! That was the problem. I changed the SetRegView and now it works.
