I need to append an env variable in Path along with a semi-colon. currently, I use
${EnvVarUpdate} $0 "PATH" "A" "HKLM" '$2'. $2 has path value. it works. however, I need to add; after path value. when I do this, it keeps adding every time when running the installer. I need to add it only if it is not present. there is no overwrite option in the EnvVarUpdate library. other than using conditions, is there any methd.
append env varable only if it is not present

The EnVar plug-in maybe?
i am using plugin itself
EnvVarUpdate is not the same as the plug-in
will check on this...Thank you
If I remember correctly, EnVar strips the final semicolon off the end of the full string before it writes it. I don't know if older Windows cares if there is a semicolon on the end or not, but it works on windows 10 without a semicolon on the end.
