After all this years I dont understand yet where is the correct place for my own plugins.
If I put then in, for example, \Win81PE\Projects\Win8.1SE, they will work, but an Update Exact and Secure will delete them.
And when they are in MyPlugins they will not work (are they processed too early?) , for example:
<Errors>
- [1] Error in Script [WordPad for testing] (MyPlugins\Apps\MsWordPad.script)
[Error] RegHiveLoad - Hive file [%target_sys%\config\software] does not exist (RegHiveLoad,Tmp_Software,%RegSoftware%) (Line 212)
