Die Hilfedatei von InnoSetup ist eigentlich sehr gut:
Zitat:
To embed a double-quote character inside a quoted value, use two consecutive double-quote characters. For example:
"This "" contains "" embedded "" quotes"
The Setup Compiler would see that as:
This " contains " embedded " quotes
If you want the value of a parameter to be a single double-quote character, use four double-quote characters: """". The outer two are needed to surround the string in quotes; the inner two are used to embed a single double-quote character.
