IB Not Connecting

[x703jko]

Installed NT7 (latest, multibroker) on a new laptop. When I go to connect to IB I get an error telling me that TWS (944.3) cannot find javaw.exe.

However, my installation does have javaw.exe installed.

Any thoughts?

Thanks. Jeff

Same here; typical Windows ****!!
Older solutions on the forum don't work.
Java's screwed up, so I can begin a whole new installation.
NT deserves a better operating system!!

I don't seem to have the same problem on my dell workstation which is also Win8.1 I do notice that on the W/S Java installed to Windows/System32 whereas it's in some other folder on the laptop.

Hello,
Please follow the instructions below.
1. Locate javaw.exe located in the following directory:

• C:\Program Files\Java\jre1.8.0_25\bin(Note your version may be different from jre1.8.0_25)

2. You are going to COPY the javaw.exe file to the 'clipboard' (right-click Javaw.exe and select copy)
3. Now paste it into the following two directories:

• C:\Windows\System32
• C:\Windows\SysWOW64

Please let me know if you are unable to connect to Interactive Brokers after following the instructions provided.

Ok; now I really need help!
New install of Windows 7, NT en TWS; same problem.
This took hours!

The last time I copied javaw.exe to C:\Windows\System32, everything spaced!
So suggestions please for Windows 7;
I don't see C:\Windows\SysWOW64 in all that Windows junk.

Thanks to persistent support, it works again!!

Please note:
• Windows 32 bit doesn't have a SysWOW64 folder
• Do try to browse and locate the java.exe file first;
(C:\Program Files\Java\jre1.8.0_25\bin(Note your version may be different from jre1.8.0_25)
it may only be a shortcut-link problem.

Thanks guys, you went beyond your duties!
