change installer

We used to installed by InstallShield before.

but that is so old and low version that I want to change
intaller .

the problem is when install program start, it must delete
ex-version program and then load program but occur error.

ex-version program regist on registry with a GUID
and NSIS installer is not.

the error is

Error installing iKenrnel.exe(:0x10000)

when ignore error and progress install,it makes another same progrem. (so there is a two same icon in window)

please help me to change installer

I don't belive the GUID registry key has anything to do with your issue with the iKernel error.

Take a look at this support article from Microsoft.

Also, according to InstallShield, the error can also occur if you do not have sufficient COM permissions. (They also tell you how to manually fix it on problem PCs.)
