[R] Making Package, Chm error, Html Help Workshop

[TEMPL Matthias]

Hello,

When building my package (R CMD check) following error message occurs:
 ...
  varinf.plot  text     html     latex      example
  x            text     html     latex      example
make[2]: *** No rule to make target `disclosure.chm`. Stop.
cp: cannot stat 'D:/Programme/R/rw2010dev/disclosure/chm/disclosure.chm`: No such file or directory
make[1]: *** [chm-disclosure] Error 1
make: *** [pkg-disclosure] Error 2
*** Installation of disclosure failed ***
Removing `D:/Programme/R/rw2010dev/bin/disclosure.Rcheck/disclosure'
 ERROR
Installation failed.

It seems, that there is a problem with HTML Workshop. No chm´s were built.
When I uninstall the HTML Help Workshop and remove the entry in the path environmental variable and doing packaging after this, the same error occurs.
I´m sure, that I have written the right entry (the path of the HTML help Workschop, where the hhc.exe file is) in the path of the environmental variable as the instructions said.

(Windows XP, Intel, R 2.1.0, HTML Workshop 1.32)

Has anybody seen such a problem before?
Can anybody give me a hint, please?

Thank you very much,
Matthias
