I used perl with TWslink before and it worked great! But my machine crashed and I am having a lot of issues with the latest version and latest platform Win 10.

Following are the issues I found so far:

Prob 1: (win32) XP

I had an old laptop with with Windows XP Pro (SP3) - the latest TWslink won't install, getting the following error:

C:\WINDOWS\system32\twslink2.dll

Unable to register the DLL/OCX: RegSvr32 failed with exit code 0x3

So the latest download can't be used

Prob 2: (win32) XP

I had an old version of TWslink from 2013 - it installed and the perl wrapper worked with ActivePerl 5.14 but orders are not getting placed.

It goes through sample.pl, makes the connection but pending orders do not show up in IB

Prob 3: (win64) Win 10

Installed Visual Studio 2015 (Community edition) and tried to build example 'cpp'. It migrated the project and it is still trying to build the Win32 version. A proper project has to be created.

After Build , running the program as no affect. Stepping in shows that the dll is not getting loaded:

TWSLink2Wrap::Load returned false

The good thing is that C# example seems to work after Building. Connection is made through the GUI

Let me know what else I need to try

Hello Sir,
i am very sorry but win xp is not longer supported.
Also in win7 and win 8.1 i do not longer any tests because Microsoft pushes
Windows 10.

Also 32 bit architecture is deprecated. Please move to a 64 bit Windows 10.
It will remove various problems.

If you have concerns about privacy, there are various tools which can help here.

Now I am using Win 10 and the perl wrapper example "ap_perl_5.14._b1401_win32_twslink_2100" is working with ActivePerl-5.14.3.1404-MSWin32-x86-296513 - but no order is getting placed

I think the important message in the log is:
"20180110 23:17:29:540; 7992;error;API;;API-error: the contract description specified for msft is ambiguous. code=200 id=11"
