Points of My Scenario:
1. I purchased the following model server:  HPE PROLIANT DL380 GEN9 E5-2620V4
2. I am required to make it a a VMware ESXi server
3. I must install the latest updated ESXi 5.5 version
REQUEST: Please provide me a link (or instructions) to the latest updated ESXi 5.5 ISO for this model server.

This is a newer model, the latest one is Gen 10.   You may want to reconsider 5.5 as it is end of support, GEN9 support the latest build of ESXi version, 6.7u2

If you still want to install 5.5 and have all the drivers for the HP build the link below has the ISO CD

I do not assume that the the author asked the question because they haven't paid annual support fee so therefore cannot upgrade the license, which is commonly the case when working on 5.5 these days. I have seen this scenario many times.

VMware will make you pay a penalty in this case to renew support on those licenses, which after a few years grows to be more than simply purchasing new licenses which many choose to do instead.

For these environments if the client cannot budget the cost of new hardware + new software, they are probably on a constrained budget and the new hardware isn't available that supports or is certified for the old software, they can often choose to instead buy used hardware to upgrade their existing infrastructure.

For example, Dell R710's can be quite the powerhorses with upgraded CPUs for most applications. You could buy 2-3 spare parts for every component as well as a kind of built-in insurance policy or self-servicing warranty, and still only spend a few thousand dollars total on the total cluster. In the same budget year perhaps purchasing new ESXi licenses is also possible due to the incredible savings in hardware cost, then the hardware can be replaced with new hardware in subsequent years IT budgets.

For other institutions, operating without vendor support isn't even an option they can accept. Sometimes though, priorities have to be made.

Again I don't assume this is the case necessarily for the author, but I do recommend looking at the used hardware market. There are so many really incredible servers on eBay looking for a good home, at outrageously low prices, that can be used for 5.5.
Paul SolovyovskySenior IT AdvisorCommented:
If using 5.5 on older hardware you are at risk of vulnerabilities since updates are no longer deployed and you don't get to take advantage of the newer hardware as you have to dumb things down for 5.5.  In most cases Essentials (under $500) or Essentials ($4500) plus work well in environments that have under 3 hosts.  

On the other hand you can use the ESXi host to run several embedded ESXi hosts on an eval license if the goal is for training purposes.

I wonder if the Author of the question can access that link ? as end of life software can only be accessed if you had licenses for it.

and there will be no ESXi 5.5 downloads of the trial anymore. Since ESXi 6.7 is current.

I wonder why only ESXi 5.5 ? (also according to the HCL he also needs 5.5 U3)
waltforbesSenior IT SpecialistAuthor Commented:
Hi all, please view clarifications below:
1. We (company) are using extended support for 5.5.
2. Our other ESXi hosts are on legacy hardware, and are using 5.5 U3.
3. We are limited by an enforced desktop environment that doesn't yet support full management of the latest ESXi version.
4. In the meanwhile, we have to deploy the 5.5 U3.
5. The desktop environment team working toward fully supporting the higher versions - but that's not for the immediate future.

REQUEST: If 5.5 U3 is no longer available, please provide me the equivalent link for 6.7 - I will force the desktop environment issue (wish me luck)! :-)

If you have extended support you'll be able to download ESXi 5.5.

Download is here

You will need your VMware login and password to download.
