Talk:File Association

I have a problem, while trying to associate a file, under Windows XP, everything works fine, but on Windows 2000, when I try to open a file, it looks like the path is not managed in the correct way, this is the way the file path is being sent on my application c:\prog~1\archi~1 so, i don´t know what´s going on, i´d really apreciate your help.

I think the problem is in this line

 WriteRegStr HKCR "ReportUncompressor.Script\shell\open\command" "" '"ReportUncompressor.exe" "%1"'

The 'OptionsFile' correspondant Registry key is only deleted when the association was in possession of another application before.

I had to change the line

   WriteRegStr HKCR "OptionsFile\shell\edit\command" "" \
   '$INSTDIR\execute.exe "%1"'

to:

   WriteRegStr HKCR "OptionsFile\shell\edit\command" "" \
   '"$INSTDIR\execute.exe" "%1"'

(Put quotation marks around the path to my execute.exe).

Otherwise when opening a file its path got truncated something like: c:\Prog~1\blabla~1\. My system is Windows XP, haven't tested it with other versions.

One other thing; you may also have to update the user's explorer fileexts list before a file association change actually takes (the items in this list override those in HKCR).

 HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts

Hi. I've tried this using NSIS 2.44 and this doesn't seem to work. According to the compiler output the file is included, and there are message about registerExtension/unregisterExtension, but when i install the software and try to open a file with my extension, windows open the usual window asking which software should be used. The example on this page is fairly straightforward, i copy/pasted it and i can't see what i could have done wrong... :-(

If i use regedit, it seems that on my computer most extensions are associated with something identifying the file (mimetype or something else i dont know). While if i run my installer, the key "My Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.myext" has keys REG_SZ set to the executable i give in first arg to registerExtension... i'm getting confused somehow.
