IPersistFile: Save error when installing shiny app without admin privileges

During an installation of a RInno generated shiny application performed by a user without administrator privileges the installer will generate two `IPersistFile: Save` errors. One when attempting to create the start menu link and another when attempting to create the desktop shortcut link.

```
Creating shortcuts...
C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Your appname4.lnk
IPersisteFile:Save failed
Access is denied
```

```
Creating shortcuts...
C:\Users\Public\Desktop\Your appname4.lnk
IPersisteFile:Save failed
Access is denied
```

These are caused by the paths generated by the Inno administrator specific variables `commonprograms` and `commondesktop`, which refer to locations visible to all users, not just the current user. These can be replaced by `autoprograms` and `autodesktop` which will adjust automatically depending on the privilege level.

Search this page for `Auto Constants`.
