I use cacls on all directories and files in the SetUp program for the COM server. Works great all of the time. here's some sample code:

* do cacls.cmd for read/write access 
	
IF ! EMPTY(lcCompName)
* create a temp batch file
*data dir
STRTOFILE([cacls "]+lcPath1+[" /E /G IUSR_]+lcCompName+[:W] + CHR(13)+CHR(10),THIS.cAppStartPath+"temp.cmd",.T.)
STRTOFILE([cacls "]+lcPath1+[" /E /G IWAM_]+lcCompName+[:W] + CHR(13)+CHR(10),THIS.cAppStartPath+"temp.cmd",.T.)
STRTOFILE([cacls "]+lcPath1+[" /E /G IUSR_]+lcCompName+[:R] + CHR(13)+CHR(10),THIS.cAppStartPath+"temp.cmd",.T.)
STRTOFILE([cacls "]+lcPath1+[" /E /G IWAM_]+lcCompName+[:R] + CHR(13)+CHR(10),THIS.cAppStartPath+"temp.cmd",.T.)
*error log dir
STRTOFILE([cacls "]+lcPath2+[" /E /G IUSR_]+lcCompName+[:W] + CHR(13)+CHR(10),THIS.cAppStartPath+"temp.cmd",.T.)
STRTOFILE([cacls "]+lcPath2+[" /E /G IWAM_]+lcCompName+[:W] + CHR(13)+CHR(10),THIS.cAppStartPath+"temp.cmd",.T.)
*app temp dir
STRTOFILE([cacls "]+lcPath3+[" /E /G IUSR_]+lcCompName+[:W] + CHR(13)+CHR(10),THIS.cAppStartPath+"temp.cmd",.T.)
STRTOFILE([cacls "]+lcPath3+[" /E /G IWAM_]+lcCompName+[:W] + CHR(13)+CHR(10),THIS.cAppStartPath+"temp.cmd",.T.)
*general temp dir
STRTOFILE([cacls "]+lcPath4+[" /E /G IUSR_]+lcCompName+[:W] + CHR(13)+CHR(10),THIS.cAppStartPath+"temp.cmd",.T.)
STRTOFILE([cacls "]+lcPath4+[" /E /G IWAM_]+lcCompName+[:W] + CHR(13)+CHR(10),THIS.cAppStartPath+"temp.cmd",.T.)
*individual data files
FOR lnI = 1 TO lnFileCount
 STRTOFILE([cacls "]+lcPath1+[\]+laDataFiles(lnI,1)+[" /E /G IUSR_] +lcCompName+[:W] + CHR(13)+CHR(10),THIS.cAppStartPath+"temp.cmd",.T.)
