Thank you for the feedback. That's good to know.

Just out of curiosity, if you set AssumeNonNeg to False in the beginning,
then later change it to True by itself, would it work? For example...

SolverOptions MaxTime:=100, Iterations:=100, Precision:=0.000001,
AssumeLinear _
:=False, StepThru:=False, Estimates:=1, Derivatives:=1, SearchOption:=1, _
IntTolerance:=5, Scaling:=False, Convergence:=0.0001, AssumeNonNeg:=False

'// Now set it correctly...
SolverOptions AssumeNonNeg:=True

Thanks all,

Finally i got a solution (Might not be good for all kind of Solver
Problems)
for my case... I just reduced the number of solver options controlled by
VBA...Previously i had written the code such that it controls all the
solver
options...Now i reduced it to only my requirements and setting other
options
to default...Now it works...

Line which caused the error:

SolverOptions MaxTime:=100, Iterations:=100, Precision:=0.000001,
AssumeLinear _ :=False, StepThru:=False, Estimates:=1,
Derivatives:=1,SearchOption:=1, _IntTolerance:=5, Scaling:=False,
Convergence:=0.0001, AssumeNonNeg:=True

Modified Line which worked for me:

SolverOptions MaxTime:=100, Iterations:=100, Precision:=0.000001,
AssumeNonNeg:=True

All other options were set to default...

Thanks once again for all your valuable inputs...

Hi !

I just want to say I have encountered the same problem,

"Solver: An unexpected internal error occurred, or available memory was
exhausted"

It happened to me using both the italian and the english
version,moreover I
have used Excel 2002 v. 10.67;
sometimes it was sufficient to update the solver references, then save
and
try again; if it doesn't work try to close the program and start it
again...today I could solve this problem three times but I don't know
why!

Hi
Very first time when i ran, the Msgbox gave me False...From then on it
gives
me True everytime...I suppose it should give TRUE as per what u say...
But this does not solve my problem...
Yeah...ofcourse i included the SOLVER.Auto_Open at the beginning of my
code...
What other possibilities u feel are there to solve this problem...?
Thanks,

Hi. That is interesting. Did you run your code with the following
line at
top?
The line just deletes a small sheet within Solver, and re-builds it.
I've
never really understood why it needs to be re-built each time Solver
is
loaded normally...perhaps it updates some internal DLL references or
something. I'd be curious on your reply, as this sometimes happens
with
later versions of Excel as well, However, I've not experienced this
issue
with Office 2003.

Sub Your_Code()
SOLVER.Auto_open ' No harm, re-build it anyway...

'// Your code here...
'// etc...
End Sub

Perhaps at a later time, you can test it with the following:

Sub YourCode()
If Not SOLVER.AutoOpened Then SOLVER.Auto_open
'// Your Solver routine below...
'// etc...
End Sub

Hi Dana DeLouis,
Thanks for the initiative.
The Message box gives me the message "False".
I use english version of Excel.
Curious for your reply...

Hi. This will not solve your problem, but could you do me a favor
and
run
this at the start of your macro. I'd be curious what your MsgBox
says.
Thanks.

Sub Your_Code()
MsgBox SOLVER.AutoOpened 'Display Flag
SOLVER.Auto_open ' No harm, re-build it anyway...

'// Your code....
End Sub

Are you using the English version of Excel?

Thanks DucA for the updated link.

But after contacting microsoft they say that the fix is
available only
on
a
chargeable basis. I could read the following sentence from the
microsoft
support page
http://support.microsoft.com/gp/prof...boundary/zh-sg
as "If a problem is determined by Microsoft to be the result of
a
defect
in
a Microsoft product, the customer will not be charged for that
incident".

Could anyone or any MVP's clarify me...

Thanks,
