Flash builder error installing some plug-ins

Hi there,
I cannot install Flash Builder plug-ins because of this error that appears every time I try to do so. I have contacted the support from Adobe and it passed almost 2 weeks and no answer from them. Can I get some help from you experts ? What I did wrong ?
Thank you !
