Previously I have used CNA 4.1 without problems.

Recently installed CNA 5.0 and upon running the app received a java error "Could not create the Java virtual machine"

Uninstalled this and went back to 4.1 which operated fine.

Have just installed CNA 5.1 and it give the same java error again.

Uninstalled 5.1 and installed 4.1 and its all fine again.


Has anyone else come across this and is there a resolution on how to fix.


BTW have also tried different JRE editions such 1.4 and 1.5.

Current:

M:\>java -version

java version "1.5.0_11"

Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_11-b03)

Java HotSpot(TM) Client VM (build 1.5.0_11-b03, mixed mode, sharing)


edit: should also mention that I have tried installing in different DIR's and changing the security to "full control" inheritive.

i have similar Problems running 4.1 everything is fine -> uninstalled 4.1 and installed 5.1 -> installation is O.K. but Application does not start ! No Error Message. Does anyone have an Idea how to troubleshoot / Trace the Start of the App. Problem in my case is on W2k3 Sp1. I have also installed on XP where everything is O.K.

Hi,


I guess you have installed NA 5.1 on a machine which has I.E 7.0. If you install NA 5.1 on WinXP or Win2K3 which has I.E 6.0 then it works fine.

OK Found the fix.


after a standard install in the default directory.


in dir "C:\Program Files\Cisco Systems\Cisco Network Assistant\startup" find file "startup.properties"


Edit in txt editor.


Third line in my case: JVM_MAXIMUM_HEAP=1024m


I changed this to JVM_MAXIMUM_HEAP=768m

(I have 2G of Ram)


All good!!!
