I just installed version frontlinesms

I'd love to use version 2 but it seems it doesn't have database connection at this moment.

so I reverted back to previous version.

While running and connecting the phone I encountered this error.

"Runtime error #3(trap)"

and from the Pop-up "Unexpected Error" window

I got this message from Details section

How can I fixed it.

BTW, I tried to uninstall and reinstall it, the same error appears.

Anyone encountered this?

Hello Azaleo,

Could you kindly assist us with information concerning the phone model you are using with FrontlineSMS so that we can trace out the problem?



Hello Sila,

Thank you for your reply. Ok will instal v2 again, will both version utilize the same modem? I presume there will be no conflict.

Hi Geoffrey,

I am using zte mf627, i have tried this modem with frontline v1.6.16.3 but run them on my laptop and they are working fine. When install it my desktop pc i wil give that error.
Btw, the pc specs are pentium 3 1ghz, 384mb ram.

What is the min pc requirement for frontline?


Hi Leo,

The specs seem ok to us. We are looking into the problem and should get back to you in a short while.



Hi Leo,

We have been able to reproduce this problem. If it works on your laptop then there might be a problem with the software on the desktop. What operating system is it using and would it be possible for you to inform us which version of Java is installed in the desktop?



Hello Geoffrey,

Sorry for the late reply, I just return from a convetion.

My Desktop is freshly installed, a window Xp sp 2 and no other programs installed.

I think the Java is ver 7 from this

What i think is. during the windows installation, i remember some file are missing from the disc so I just skip them. Maybe its one of the reason.

I will probably install it again.

BTW does frontlinesms work under windows 98 environment?

I think i don't need the windows xp features.

or What Ubuntu Linux can you recommend?



Hi Leo,

This could be a problem since we have not encountered any problems of this kind when we install the software on a Windows XP machine.

The software works on both Windows 98 as well as Ubuntu. You could try using Ubuntu 11.04 and above. You can down load the linux version here.
