I have been working with Compaq's PDA with Windows OS 3.0.11171.
I can install Windows SQLCE 2.0 developed by a vendor on it without any
hitch.

But recently I tried to install the same Microsoft SQLCE 2.0 on a
Symbol PDA which has Windows OS ver 4.20.1081 build 13100 on it. I got
an error message : The program is not compatible with the current OS
and therefore may not run on the device.

If I still choose to install it, it does get installed but some
subsequent applications don't, and I wonder whether that is because of
the warning about SQLCE 2.0 incompatibility. At any rate, I would like
to know how to be able to develop and install MS SQLCE 2.0 across
multiple OS versions.

I would be grateful for any advice.

Which Symbol device? We use a few of them (PDT8100, PPT8800, and MC50) and
have no trouble with SQLCE 2.0, even when running on a device that is using
the latest Mobile 2003 SE. My guess is that SQLCE 2.0 is not what the
complaint is about... could it be complaining about the "vendors" software
and not SQLCE 2.0?

I am using Symbol MC 9060 (pxa 255 processor).

Quite independent of the vendor's software, I do get a warning about
incompatibility when I try to install MS SQL CE 2.0 on the PDA.

Is this URL relevant here :
http://support.microsoft.com/?scid=h...ticle%3D290311

It says : "A database created on a Windows CE 2.0 device cannot be used
on a Windows CE 3.0 device, and vice versa."

Ok, so it is SQLCE 2.0 that is being complained about. (I have not used the
MC9060.) I don't think the complaint is about an actual database (a .SDF
file) being created on one OS version and being used on another. Perhaps
you'll get a better response posting to the microsoft.public..sqlserver.ce
newsgroup. I'm using SQLCE 2.0 on all the available OS's and get no
complaint. Sorry I couldn't help...

That's great to know. We don't use a CAB style install; we have a
proprietary device instal that copies files and registers them, so we never
see that message.
