Certificate problem

Hi,

I hope someone might be able to assist with the following error.

On updating the SARS e@syfile application the updates stops so you will update the Adobe Air application. The Adobe Air application gives successful installation message (see fig1) but thereafter the e@syfile installation continues and suddenly the following message (fig2) is received from Adobe Air and the e@syfile stops running and installation fails.

.

I have uninstalled Adobe Air twice and reinstalled but to no avail.

I am not sure how to fix this dilemma.
