Problem with crystal 4.6 and VB6

Here is the situation, on a clean windows installation (tried so far in 98 and 2000) the following code is used to retrieve a report to the screen. But sadly it does nothing, the result in the .status property after the .action = 1 line is -1 where actually a successful report shows 3.

VB Code:

'use ADO to connect to a Access 97 DB.
 
CrystalReport1.Connect = "Provider = Microsoft.Jet.OLEDB.4.0;" & 
App.Path & "\config.mdb;UID=sa;PWD=12345;"
Me.CrystalReport1.DataFiles(0) = App.Path + "\db.mdb"
 
'call the report which is stored in the app's path.
 
CrystalReport1.ReportFileName = App.Path + "\boent_rep.rpt"
CrystalReport1.Destination = crptToWindow
CrystalReport1.DiscardSavedData = True
 
 
'before this lines, I go thru several steps to get the formula.
 
CrystalReport1.SelectionFormula = formula 'whatever formula is
 
'call the report.
CrystalReport1.Action = 1

THe viewer doesnt show at all, but Im postive the program executes all the lines. As I have said, the status property might tell me the answer but I cant find any description of what a -1 result means. Any help will be appreciated.

*bump* :)

this problem doesnt occur on every machine, in some XP and 2000 machines it worked ok, but in the machines I installed windows (98 and 2000) it was no likely to work.
