Run-time error 339, MSFLXGRD.ocx a file is missing or invalid

Good day to all,

I'm currently installed one of investment application and able to run as
normal.
The error message (as per above subject) came out while I'm trying to click
at any button in the application.

I'm using windows Vista 32bit platform, and already run "regsvr32
MSFLXGRD.ocx", the message succeeded appeared but the error 339 still occured.

Please help how to rectify this error. Any solutions?

Need helps,
Tini

Someone else resolved the issue by first un-registering the control and then
re-registering it. Hope it helps.

From their post:
The problem is resolved, but not how you would expect. Even prior to the
suggestion above, I had already tried re-registering the control with
REGSVR32 running as administrator, but that didn't solve the problem.
However, if you first UN-REGISTER the control with the REGSVR32 /U option,
then re-register, all is fixed. There was absolutely nothing wrong with the
control or the build, it's totally a problem with how InstallShield interacts
with Vista, and how it registers items that require DLLRegisterServer.

it worked for me through this command - type this on your RUN window
(Windows+R)

regsvr32 \Windows\System32\msflxgrd.ocx /u

PNUTT,
You are the man. Thank you so much for posting this information. It
helped me solve a problem with another .ocx file that wasn't installing
with installshield as well as the one listed. --JF
