I use [Run] section to modify the merit value of some codecs with commandmerit.exe that supports command-line.

So the syntax is:

Commandmerit.exe "{E2B7DF46-38C5-11D5-91F6-00104BDB8FF9}" "0x800000"

{E2B7DF46-38C5-11D5-91F6-00104BDB8FF9} is the CLSID of the codec and 0x800000 is the value of the new merit, but when I put this line in [Run] section :

Filename: "{app}\Commandmerit.exe"; Parameters: ""{F8FC6C1F-DE81-41A8-90FF-0316FDD439FD}" "0x10000000""; WorkingDir: "{app}"

The flowing error is displayed:

Mismatched or misplaced quotes on parameter.

If I put this line:

Filename: "{app}\Commandmerit.exe"; Parameters: """{F8FC6C1F-DE81-41A8-90FF-0316FDD439FD}" "0x10000000"""; WorkingDir: "{app}"

The flowing error is displayed :

Unknown constant ...... use two consecutive"{" if .....

If I put this line:

Filename: "{app}\Commandmerit.exe"; Parameters: """{{F8FC6C1F-DE81-41A8-90FF-0316FDD439FD}}" "0x10000000"""; WorkingDir: "{app}"

Then no error is displayed but it seems that the commandmerite.exe don't understand the parameter, so after the installer finishes the merit still unchanged.

To add quotes to a parameter, you must double up each quote, and then put quotes around the entire value.

Your second attempt was close but you forgot the middle ones.

Filename: "{app}\Commandmerit.exe"; Parameters: """{F8FC6C1F-DE81-41A8-90FF-0316FDD439FD}"" ""0x10000000"""; WorkingDir: "{app}"
