no, but you can try to read it first, and only write if it sets the error flag (or returns empty string)

Yes, that's right. The best way is write your own macro ;-)

I have a long list (50) of RegKeys like this:

WriteRegStr HKLM "Software\x\x" "abc" "def"
...
WriteRegStr HKLM "Software\x\x" "asd" "gfd"


I only want to write them if they not exist. Can you please give me the code for this problem??

Thnaks for your help

Yes, I can. Sorry for that Czech names ;)

I can also provide script which converts .reg file into NSIS commands like ${registry::________} ... ... ... ...

The script was too big.

Copy / paste?

Try something like ${ZapisReg} "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion" "ProductId" "this is really CRAP!" "REG_SZ"

Just use a macro:

!macro _WriteReg Type Root Key Name Value
  Push $R0
  ClearErrors
  ReadReg${Type} $R0 `${Root}` `${Key}` `${Name}`
  Pop $R0
  IfErrors 0 +2
    WriteReg${Type} `${Root}` `${Key}` `${Name}` `${Value}`
!macroend

!define WriteRegDWORD `!insertmacro _WriteReg DWORD`
!define WriteRegBin `!insertmacro _WriteReg Bin`
!define WriteRegStr `!insertmacro _WriteReg Str`

Nice. Why should I do it simply if I can do it intricately? :)
